PAPER BAG.

SPECIFICATION forming part of Letters Patent N0. 349.838. datedSeptember 28, 1886.

Application tiled March 30, 1886. Serial No. 197,163. (Model.)

T0 all whom t may concern:

Be it known that I, WARREN C. FAGELEY,

a citizen of the United States, residing at Philadelphia, in the countyof PhiladelphiaJ and State of Pennsylvania, have invented certain newand useful Improvements in Paper Bags; and I do declare the following tobe a full, clear, and exact description of the invention, such as willenable others skilled in the art to which it appertains to make and usethe same, reference being had to the accompanying drawings, and to theletters and figures of reference marked thereon, which form a part ofthis specification.

, Figure l is a view of the blank or pattern sheet before it is folded,the dotted lines indicating the lines of folding or creasing. Fig. 2shows the satchel and square bottom folded before the side flaps of thebody or tube are united and pasted, with one side broken away. Fig. 3 isa vertical section, enlarged, of the lower part of the bag, taken on theplane indicated by the dotted line m x of Fig. 4. Fig. 4 is aperspective View of the bottom of the bag.

This invention relates to the production, in a novel manner, of satcheland square bottom paper bags, as will be fully understood `from thefollowing` description, when taken in connection with the annexeddrawings.

My improved method or process of manufacturing paper bags consists infirst producing from a sheet of paper the blank or pattern sheet shownby Fig. I of t-he annexed drawings. Suitable machinery will be employedfor the purpose.

The dotted marks a a. determine the lines or creases for folding the twoside flaps, A A. The dotted line n on the flap A indicates the width ofthe marginal portion B, which in the finished bag overlaps the edge ofthe flap A and is pasted to it. The bottom of the bag is produced fromthe extension or Hap C, which may be of any desired length, and whichhas tapering ends C O, that encroach somewhat into the lower ends of theflaps A A, and are folded or creased, as indicated by the dotted lines ac I) c d, forming what is known as a Satchel bottom. Vhen this bottomextension of the body of the bag is folded as shown by Figs. 2 and 3,the tapering ends C C thereof form two thicknesses of paper andeffeetually close and reenforee the bag at its bottom corners. Thebottom extension having been thus folded, the two flaps or sides A A arepasted together along their longitudinal edges, as above described. Themarginal portion e of said extension C is then pasted upon the outsideof the flaps A A. I thus make the bottom of the bag scamless7 and of butone thickness of paper.

It is obvious from the above description that the Satchel bottom of myimproved bag can be made of any desired width, and that the bag willstand alone when unfilled. It will be observed that the blank is of theform of an oblong rectangle extending from the lower edge of which isthe flap or portion C, having tapered sides. Fig. lshows the blank withdotted lines indicating the lines of fold. Having prepared this blank Ifold the portion C along the line b upon the body portion. I then foldback this portion C upon itself' along the line c. Flap A is then foldedover along line a. Flap A is folded on its line a, and the marginalportion B pasted upon the flap A. The marginal portion c of the portionC is folded over the lower edges of the portions A A and pasted thereto,as shown in Figs. 3 and 4, which finishes the bag..

Having described my invention, I clain1- l. The method herein describedof making satchel and square bottom paper bags, consisting in firstproducing the blank described, folding the extension C upon the bodyportion of the blank, then back upon itself, then folding the two sidesA A and pasting them together along their longitudinal edges, andfinally pasting the marginal portion of said extension upon the outsideof the said flaps, as herein specified.

2. As an improved article of manufacture, a paper bag having a seamlesssatchel and square bottom formed of an extension of the body ofthebag-blank and provided with reenforcing corner folds, and an outsidemargin pasted upon the two united side1laps,substan tially as described.

In testimony whereof I aix my signature in presence of two witnesses.
